EMBossING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 572,197, dated December1, 1896.

i Application filed July 17, 1896. Serial No. 599.509. (No model.)

To LLZZ whom it may concer/1,:

Beit known that I, EDWARD S. DE TAM- BLE, a citizen of the UnitedStates, residing at Indianapolis, in the county of Marion and State ofIndiana, have invented certain new and useful Improvements inEmbossing-Machines, of which the following is a specifica tion.

The object of my said invention is to provide a means whereby anembossing-machine may be employed to ornament curved or circular woodenstructures, such as bicyclewheel rims, mud-guards, &c.

An embossing-machine provided with attachments embodying my saidinvention will be first fully described and the novel features thereofthen pointed out in the claims.

Referring to the accompanying drawings,V

which are made a part hereof and on which similar letters of referenceindicate similar parts, Figure l is a perspective view of suchanembossing-machine; Fig. 2, a central vertical sectional view of theupper end thereof, and Fig. 3 a detail sectional view on the dotted line3 3 in Fig. 2.

In said drawings the portions marked A represent the frame of themachine; B, the main roll-carrying shaft; C, the 'embossingroll ordie-spindle; D, the burner therein, and E a guide-supporting shaft orrod.

The frame A is a strong, heavy frame suitably arranged to carry themechanism, and is preferably mainly in the form of heavy castings, asshown. l

The shaft B is mounted in bearings in the heavy vertically-adjustableframe B', which is mounted in ways in the sides of the frame A, and atthe upper end extends out into substantially the form `of a table, butwith an open upper side. This vertically-adj ustable frame or table isadapted to be raised and lowered quickly to and from certain determinatepositions by a rock-shaft 1, having cams 2 and operated by a hand-lever3. Said cams 2 operate against the blocks 4, which are connected to therods 5, the upper ends whereof are seated in sockets in the frame B.These rods 5 are screw-threaded and enter screw-threaded perforations inthe blocks 4. They are provided with bevel-pinions 6,which engage withcorresponding pinions '7 on J[he shaft 8. By this means these rods 5 maybe simultaneously revolved and thus the distance between theblocks 4.andthe frame B adjusted. I have shown a sprocketfwheel 9, having asprocket-chain l0, (running to a suitable hand-operated shaft, notshowin) as a means for revolving this shaft; but obviously thesprocket-wheel. 9 might be a plain handwheel and the shaft 8 thusoperated directly by hand or any other suitable means for the purposeemployed. Said shaft B bears the various disks b, b', and h2, whichserve to support the wooden pieces being embossed while the embossingoperation is in progress. I have shown three of thevdisks h, three ofthe disks ZJ', and one disk h2; but obviously any desired number may beemployed. These disks are shown as separated by washers and y held inplace on the shaft I3 by suitable collars.

The spindle C is hollow and carries the embossing disks or dies c, c,andc2, which correspond to the companion disks b, h', and b2 and which areengraved on their peripheral surfaces with the figures desired to beembossed on the wood. Said disks are separated by washers and securedupon the spindle in the same manner that the corresponding disks areseparated and secured upon the shaft B. This spindle is supported byheavy rollerbearings at each end and comes directly in contact with therollers C', forming the operative part of said bearings.

The burner D is a tubular burner and eX- tends within the opening in thespindle C. Securely attached to the outer end of this burner is the capD', which rests immediately within the extreme outer end of the spindleC and is adapted to support the burner, although it is not fastened tosaid spindle, and is consequently capable of remaining in its positionwhile the spindle revolves. Said cap D has anumber of fine perforationssurrounding the opening, by which the burner D is coupled thereto forthe admission of air, and the spindle C is provided with perforations atthe other end of the burner, as shown in Fig. 2, for the escape of I[heproducts of combustion. A neck or elbow D2 is connected to the cap D',and to this in turn is connected a flexible tube or hose D3, which leadsto a IOC mixer D4, to which the gas-pipe D5 leads, whereby the fuel-gas,which I prefer to use with this maehinefis suppliedthereto.

The shaft or rod E is mounted in bearings e on standards E on the frameA. These standards are slotted and the bearings are thus renderedadjustable, as plainly shown, so as to accommodate the guides to Work ofdifferent size. Upon the outer end ofthis shaft or rod are theguide-rollers E2, which engage with and support the bicyclerims whilebeing embossed.

In the machine as illustrated the provision is made for the embossing ofthree Wheelguards X, three Wheel-rims Y, and one chainguard Z. TheWheel-guards X, being in the form o f strips, although somewhat curved,may peras. Within the machine; between the bealnsS in. the freme'rhhefry'therolls' and/dies, Therilns Y being ann ular in form, if. i'S.lfeeessaiiy that' thefllls and, dies., by Which-'they et@ treated.Should be' 'outside the bearing in orderJ that they maybe removed and'replaced. It isfals'o rdesirable that the Cham-euere be Similarlyolitsid'f the beelting, for, irhile noteofnipletely connected tof getherat the ends, vit is of such formY to render, itsintroduction inside ofthefbearin gs very difficult. As the rims'Y extend a considerabledistanceabove the point Where they areoperated L ipon, it is necessarythat their upper and otherwise free portions, should be accuratelysupported in position, iny order that the Werl; may be' uniform, 'and'thefshaft E, with its"guiderolls E2, Vis provided accord ingly, saidguide-rolls being held between collars e2, as shown, which prevent themfrom moving endwise of the shaft by which they are carried, althoughleft free to revolve thereon.

'In order that the rims Y may bel removed and replacedy readilyvwithoutuneoupling the fuel hoseor tube D3, said tube is bent around andcondueted back', substantially parallell with thespindle C, to apointoutside of the rolls and dies by Which the rimsare treated.

By the machine shown I find that Iv am enabled to satisfactorily.embossthese thin Wooden parts, which have not heretofore been capable of beingsuccessfully provided with ornamentation of this character. Manifestly,from the nature of the structures to be so operated upon, ythe embossingmust not be deep, and consequently the spindle and shaft may extendoutside the bearings by which they are supported and still havesufficient strength and rigidity to perform'the Work.

Having thus fully described my said invention, what I claim as new, anddesire to secure by Letters Patent, is-

l. The combination, in an embossing-ma chine, of a main framework, anadjustable frame or table, a main shaft carried thereby and having anend which projects to the outsideof the framework of the machine, and isthere provided with supporting disks or roll- Iersl for the Work toy betreated, a spindle mounted inbearings in the main vframework andalsdertendin gtooutsfidethe frame of the machine, @11d the@ Provided,with.. embossing rolls 0r dies. a' burner Withe Said Spindle, acaploosely' monnted in the en d of said spindle' and adapted 'to remainstationaryvwhile the latter revolves: forcarrying theburn er at itsouter end, a flexible coupling connected to said cap and extending back`substantially parallel with the spindle' toz alongside the frame andtheneeto thega's-,fuel-supply pipe, and said pipe, Wherebyvvheel'frimsand similar annular stru cturesmaybe embossed upon their interior sides,substantiallyas` shown and described.

2. AnV embossing 1 machine, the spindle whereof extends tov ontside theframework thereof and .carries embossing rolls or dies thereon, and avheat-supplying tube connected to the burner-cap in the outer end of thespin.-

dle and extending then ce back alongside the spindle, to'y near theframework, thus enabling annnlar structures to be placed over thespindle and` operated upon, substantially as and for the purposessetIforth.

In Witness ivhereof'I have hereunto set my hand and seal, atIndianapolis, Indiana, this lthday of July, A'. D. 1896. V
